A study published this week – which gathered information about the retraction policies of the top 200 scientific journals, ranked by impact factor – found that 3 times as many journals in the sample (65%) had a retraction policy compared to an earlier study in a similar group of journals (21%) conducted in 2004.

Of the journals samples, 95 (65%) had a retraction policy. Of journals with a retraction policy, 94% had a policy that allows the editors to retract articles without authors’ consent.
